type "MPI_Comm" cannot be assigned to an entity of type "unsigned int" about mana HOT 11 OPEN

Hi Yuling,
At this time, we're still working on making MANA really robust. Our primary work environment for now is Cori at NERSC. For CentOS 7, we've partially ported it so that it can launch and checkpoint, but it cannot yet restart. As the project becomes more mature on Cori, we will roll it out to other platforms.
The safest thing is to check back later.

You wrote that you're using intel open mpi.  Is this Intel MPI or Open MPI?  For certain technical reasons, we require the ability to create a statically linked MPI executable.  We will fix this later.  From what I understand, Open MPI does not support statically linked executables (i.e., does not support libmpi.a).

@gc00 Hi gc00,
The kernel of the HPC in my school is CentOS 7, and the MPI version is Intel MPI. For now, I try to checkpoint the MPI job on HPC. By using DMTCP, I was able to checkpoint/restart single-node MPI jobs. However, for multi-node MPI jobs, as you said, DMTCP can only save checkpoints, but cannot restart.
When will you be able to support Linux CentOS 7? Thank you

I haven't tried MANA yet because I had some problems installing it on CentOS 7.

/usr/bin/ld: cannot find -llzma
/usr/bin/ld: cannot find -lxml2

I don't have root permission of our HPC, so I can't install the missing library. I'm working on trying to use MANA on HPC.

Hi Yulin,
The MANA for CentOS 7 is still a work in progress. But it will be possible to download the rpm packages and extract what you need there for the missing libraries.
I estimate another two weeks or so before I have it fully ported.

Hi Gene.
I will try to download the rpm package for the missing libraries. Thank you very much for your help.
And I am looking forward for the fully porting on CentOS 7.

Hi,
I had the same problem, did you solve it?

Hi, Gene
I have tried to use openMPI, Intel MPI, and MPICH to compile mana, but have encountered many problems. Which MPI should I use to compile mana, or is it because my environment is CentOS7?

Hi,
I had the same problem, did you solve it?

I solved this on the direction of a file whose location is mana/contrib/mpi-proxy-split/lower-half/README.mpich-static. After solving this, I have other questions about installing mana on CentOS 7. And i don't fix it yet.

@gc00 Hi Gene,
have you successfully port MANA to Centos 7?
Also, for multi-node MPI jobs, DMTCP cannot restart them. I hope that DMTCP can support multi-node MPI checkpoints.

HI? how about your process？ I compile the MANA succeed with MPICH in CentOS7，and save checkpoints with hellpmpi.c in local node，but when restart it fails.

@gc00 How is the status on OpenMPI supprt in MANA? Thanks!
